EveryMemoryWord Ladder
Turn COLD into WARM by changing one letter at a time, each step a real word. A free word ladder puzzle invented by Lewis Carroll - five to solve. Play it right here.
⚡ Quick answer
A word ladder turns one word into another by changing a single letter at each step, where every intermediate must be a valid word. It trains word retrieval and flexible thinking - searching memory for words that differ by one letter. Each puzzle here has a curated list of accepted words and a known short solution. The fair score is your number of steps versus your own best.
Key takeaways
- Change one letter at a time, each step a real word, to reach the target.
- Invented by Lewis Carroll in 1877 - five curated puzzles to solve here.
- Trains word retrieval and flexible thinking - finding words a letter apart.
- Fewer steps is tidier; beat your own fewest total, not a benchmark.
The word ladder was invented by Lewis Carroll in 1877, and the idea is beautifully simple: change one letter of a word at a time, with every rung along the way a real word, until you transform the start word into the target. COLD becomes CORD becomes WORD becomes WARD becomes WARM.
Play the five curated puzzles above (type each next word and we'll check it), then read on for the strategy and what it trains.
How to play
Each puzzle gives you a start word and a target, plus a list of words it will accept.
- Tap Start, then type a word that changes exactly one letter of the current word.
- Each new word must be a real word in that puzzle's accepted list.
- Keep going until you reach the target word.
- Fewer steps is better; solve all five and your fewest total steps is saved on your device.

What it trains
Word ladders are a lively word-retrieval workout:
- Word retrieval - pulling up words that match a letter pattern.
- Flexible thinking - trying several routes when one dead-ends.
- Planning - steering letters toward the target rather than wandering.
Like any single word game, it mostly sharpens this kind of word search - enjoyable practice, not a broad brain upgrade.
A strategy that helps
The trick is to think about which letters you ultimately need and change those toward the end:
- Compare the start and target letter by letter to see what must change.
- Change one 'target' letter early if it still leaves a real word.
- If you stall, back up a rung and try a different intermediate word.
The honest way to read your score
Compare your step count only to your own past solves. A shorter ladder is a tidier solution, but getting there at all is the real win.

⚠ When to talk to a professional
This is a non-medical word puzzle for fun and practice, not a test of intelligence, vocabulary level or brain health. Performance varies with practice and familiarity. If you're worried about a real, persistent change in your thinking or word-finding, speak with a qualified healthcare professional rather than reading anything into a game score.
